PATENT GRAIN-BINDER TRIP MECHANISNE.,

SPECIFICATION forming part of Letters Patent No. 426,550, dated April 29, 1890.

Application filed September 13, 1889. Serial No. 323,964. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN F. SEIBERLlNG, a citizen of the United States, an d a resident of Akron, county of Summit, and State of Ohio, have invented a new and useful Improvement in Grain-Binder Trip Mechanisms, of which the following is a full, clear, and exact description, reference being had to the accompanying' drawings, making part of this specification. t

The invention relates to the manner of conneetin g the pitman which actuates the binderarm shaft with the crank-arm of said shaft, whereby said crank-arm is adapted to yield relatively to the pitman for releasing` and throwing` the binder-gear mechanism into action; also, to the means for locking and releasing' the sliding box through which the pitman is connected with the crank-arm, whereby it is held iirmly locked in position during the operation of binding.

ln the accompanying drawings, Figure l is afront elevation of myimproved bind er-shaft crank-arm and its pitman-connection, and Fig. l is a side elevation of the same. Fig. 2 is a front view showing the relation of the binder-shaft crank-arm to its driving-gear Fig. d detail views of the sliding pitman-box and its latch. Fig. 5 is a rear elevation showing the binder-table, binder-arm, and compressor and their relative arrangement.

The binder mechanism in its general arrangement of parts may be of the well-known Appleby type, and need not, therefore, be described in detailfurther than necessary to an understanding of my improvements.

A inthe accompanying drawings indicates the gear-shaft from which motion is communicated to the binder gear-shaft, and which ordinarily, also, is provided with the crankarms which actuate the packers. This shaft is in continuous operation and carries a crosshead A', which engages a dog a on a pinion a', from which, through any suitable train of gearing, motion is nimparted to the binder mechanism in a well-known manner.

B indicates the binder-arm shaft, and B the crank on one end of said shaft for actuating it, and to which a vibratory movement is imparted for vibrating the needle or binder arm by means of a pitman C, connecting it with a crank-pin c on the outer face of a gearwheel (indicated in dotted lines) on the forward end of the knotter-actuating shaft in the usual. manner.

The crank-arm B', when the binder mechanisin is at rest, occupies the position shown in Fig. l, in which it forms an acute angle with the pitman, and is provided at its outer end with an angular extension or arm B2, forming an obtuse angle with the crank-arm proper and lying in a plane parallel with the pitman C extended. This extension is slotted at its inner end, at c', to receive a perforated box e, which engages the end of the pitlnan O, and which is arranged to slide in the slot c to allow slight relative movement of the crank-arm and pitman. The arm B2, outside of the slot c', is bored longitudinally to receive a spiral spring f, and at its outer end the perforation has its walls screwthreaded to receive a set-screw f, by the adjustment of which the tension of the spring f may be adjusted as required. The spring f at its inner end bears against the box e and serves, when its tension is not overcome, to hold said box at the inner end of the slot c'.

The crank-arm B carries an arm. D for tripping or throwing the binder mechanism out of gear, and has a latch-lever G pivoted at its inner end to its outer face, said latch-lever having a hook or spur g on its outer end., adapting it to engage the outer face of the boX c when the latter is at the inner end of `the slot c and to lock and hold the box in said position.

The outer face of the arm l5 has a perforated lug` b formed on it, and the latch Ghas similar lugs g g2, the former near its pivoted,

end on the inner face and the latter on its outer face, as shown. The lug b has a pin b secured to it and passing through the lug g on the latch G. The pin b has its outer end screw-threaded to receive a nut b2, between which and the lug` g a spiral spring b3 surrounds the pin and serves by its tension to press the latch into engagement with the box c. rlhe tension of the spring b3 is regulated by adjusting the nut b2. The perforation in the lug g2 has its wall screw-threaded to receive a set-screw h, by the adjustment of ICO which the point in the throw of the crankarm at which the release ol' the box c from the latch G is effected is regulated as desired. The arrangement of the lug g2 and set-screw h is such that as the crank-arm B approaches the end of its backward throw or movement for bringing the binder-arm into position to receive the grain for another bundle it swings into contact with the end of the set-screw h, and, acting through the latter on the latch G, forces said latch out of engagement with the boX e, thereby leaving the crank-arm when in its position of rest yfree to be vibrated independently of the pitman under the action of the grain upon the compressor suliiciently to rock the arn1,D out of engagement with the dog a, and thereby to throw the binder mechanism in gear in a wellknown manner. The spring j', the instant the crank-arm is freed from the compressing action of the grain thereon, serves to thrust the box e inward, andas the pitman swings outward awayjrom the set-screw h the latch G is left free to swing inward under the tension of the spring h3, and is thereby made to engage and lock the box c at the inner end of the slot c until by the return movement of the crank-arm the latch is again withdrawn, as explained.

In IFig. 5 the arrangement of the parts described relative to the binder-arm, table, and compressor is shown, I indicating the bin derarm, I the cam thereon, K the compressor,

K the colnpressor-arln, and L the inclined binder-table.

IIaving now described myinvention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination, with the binder-arm secured to the shaft B, of the crank B', provided with the longitudinal slot arranged in oblique relation thereto and in line with the pitman extended when the parts are at rest, the journal-bearing for the pitman elastically and adj ustably secured therein, and the triparm D, operating as shown and described.

2. The combination, with the binder-arm shaft and its crank provided with the longitudinal slot and the yielding journal-bearing, of the pitman secured therein and the locking-pawl G, pivoted on the binder-arm crank and adapted to engage said yielding journahbearing, as shown and described.

3. The combination of the binder-shaft crank-arm B', provided with the slot formed therein, the journal-box e, arranged to slide in said slot, the locking-pawl G, the tensionspring f, the pitman O, the adj usting-screwf, and the trip-spring b3, substantially as described.

In testimony whereof I have hereunto set myhand this 30th day of August, A. D. 1889.
